A Rockwool Cleanroom Panel bonds two corrosion-resistant color-steel facings to a high-density rock wool core — an A-grade fireproof, sound-insulating cleanroom wall and ceiling panel made to a ≤ 2 mm/2 m flatness tolerance. Key advantages:
A rockwool cleanroom panel is a metal sandwich panel formed by bonding two color-coated steel sheets to a high-density mineral rock wool core. The steel skins give a hard, wipe-clean, anti-static surface with strong corrosion resistance, while the rock wool core delivers A-grade non-combustible fire protection plus thermal and acoustic insulation. It is the standard, cost-effective board for cleanroom walls and ceilings that need reliable fire performance without sacrificing strength.
The facing uses top-brand pre-painted steel with a controlled coating thickness, so the panel resists dust accumulation, dust generation and surface corrosion — meeting the hygiene demands of a controlled environment. Where a project needs an all-inorganic, mould-proof facing for fire compartments or wet wash-down areas, the magnesium oxide rock wool panel is the alternative; for maximum thermal insulation, see our PIR and EPS cores.
Part of Wonclean's cleanroom sandwich panel family, the rock wool panel pairs with matching ceiling systems and cleanroom doors and windows for a fully sealed, flush-finish cleanroom wall system.

Panels are produced on a high-precision automated line using top-brand color-coated steel with a controlled coating thickness for corrosion resistance. Tight tolerances (flatness ≤ 2 mm/2 m) mean gap-minimised joints, and we offer multiple cores and certified fire ratings so the panel matches your exact specification.
The rock wool core is A-grade non-combustible, with fire resistance up to 1–2 hours depending on thickness. We provide third-party fire test reports and certificates to EN 13501-1, ASTM E84 and BS 476, plus ISO 9001 and CE, on request.
Rock wool boards carry internal reinforcement to resist sagging and are made to ≤ 2 mm/2 m flatness. For export they are stacked flat, film-wrapped with corner protectors and crated in plywood boxes for long-haul sea freight, with clear unloading and handling guidance.
A single project is produced from the same steel coil batch. For large multi-batch orders we coordinate with the mill to match color, and any unavoidable variation can be zoned by room or area so it is not noticeable. RAL and custom colors are available.
Rock wool gives the best balance of A-grade fire safety, acoustics and value for general cleanroom walls. Choose the MgO rock wool panel for an all-inorganic, mould-proof facing, or PIR / EPS when thermal insulation or budget is the priority.
Sample/small orders typically ship in 10–15 days and a full container in about 20–25 days from Shanghai. Steel gauge, color, thickness and certificates are made to order — send your panel schedule and we will confirm exact MOQ, lead time and FOB/CIF/DDP pricing.
Send us your thickness, steel facing, color, fire rating, ISO/GMP class and panel quantity. Our engineers return a panel schedule, test reports and a factory-direct quotation — typically within 24 hours.

System Overview A PU Cleanroom Panel bonds two coated-steel facings to a rigid polyurethane (PU) foam core — a high-insulation, airtight cleanroom wall and ceiling panel made to a ≤ 2 mm/2 m flatness tolerance. Key advantages: Superior Insulation: Lowest thermal conductivity (λ ≈ 0.022 W/m·K) — ideal for cold rooms and controlled temperatures. Airtight & Sealed: Closed-cell foam blocks moisture and air leakage for stable conditions. Lightweight & Strong: Strong facing bond, low weight and an anti-static, wipe-clean surface.
System Overview A PIR Cleanroom Panel bonds two coated-steel facings to a rigid polyisocyanurate (PIR) foam core — a high-insulation, fire-improved cleanroom wall and ceiling panel made to a ≤ 2 mm/2 m flatness tolerance. Key advantages: Insulation + Better Fire: Near-PU thermal performance with an upgraded Class B1 fire rating. Chars, Doesn't Melt: Forms a stable char with low smoke under fire, improving fire integrity. Lightweight & Sealed: Closed-cell core blocks moisture, with a strong facing bond and clean surface.
System Overview A Duct Cleanroom Panel is a pre-insulated board for fabricating clean HVAC air ducts — a smooth metal facing over a rigid insulation core, with a galvanized perimeter for flanged jointing, made to a ≤ 2 mm/2 m flatness tolerance.
